Timing specifications​
| Parameter | SP259 (standard) | SP259i (industrial) |
|---|---|---|
| Sampling rate (MAX) | 250MHz | 250MHz |
| External clock frequency (MAX) | 62.5 MHz | 62.5 MHz |
| Embedded memory | 1 Gb | 1 Gb |
| Streaming to computer | Yes | Yes |
| Configurable pre-trigger time | Yes | Yes |
| Trigger output | Yes | Yes |
| External trigger input | Yes | Yes |
| Logic signals digital bandwidth (1) | 75 MHz | 75 MHz |
| RS232 input digital bandwidth | N/A | 1.5 Mbps |
| RS485 input digital bandwidth | N/A | 50 Mbps |
| CAN input digital bandwidth | N/A | 8 Mbps |
| LIN input digital bandwidth | N/A | 20 Kbps |
Unlike many logic analyzers that reduce sampling speed as more channels are used, the SP259 maintains its maximum sampling rate of 250MHz across all 9 channels simultaneously.
Logic inputs specifications​
| Parameter | SP259 (standard) | SP259i (industrial) |
|---|---|---|
| Number of channels (can all be used simultaneously at maximum frequency ) | 9 | 9 |
| Input impedance | 200 KΩ // 8 pF | 200 KΩ // 8 pF |
| Independent threshold circuits (for for each group of 3 channels) | 3 | 3 |
| Adjustable logic levels | 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5V | 1.8V, 2.5V, 3.3V, 5V |
| Absolute maximum voltage on any logic input | ± 25 V | ± 25 V |
Logic inputs probes connector is a standard 2.54 mm, 10 points connector. You may use other "device-to-board" wire harness to connect directly to your device under test. In this situation, it's recommended to keep the wire length under 25mm. Please contact us with any questions regarding customization of your test setup.
Industrial inputs specifications (SP259i only)​
| Protocol | Number of channels | Notes |
|---|---|---|
| CAN | 1 channel | Compatible with CAN (classic) and CAN FD |
| LIN | 1 Channel | Includes a battery input pin for voltage reference. |
| RS232 | 2 Channels | The two channels can be combined to capture a full duplex RS232 bus |
| RS485 | 2 Channels | A total of 4 input for two differential channel can be used to capture either RS485 or a full duplex RS422 |
Industrial inputs are multiplexed with the existing 9 logic channels. You can mix and match between logic signals and industrial busses, but the maximum number of channels that SP259i can capture is still equal to 9.
All industrial ports use 3 pin, 3.5mm pitch, standard terminal blocs. In case a replacement is needed, Ikalogic recommends Wurth Electronics reference: 691361100003.
